Critical Solar Mounting Hardware: Screws, Bolts, and Nuts
High-quality solar mounting relies on specialty screws, bolts, and nuts to securely fasten photovoltaic panels and racks. These components bear the mechanical loads, prevent loosening from wind vibration, and resist corrosion from outdoor exposure.
Nuts
Nuts are used together with bolts and washers to complete fastened connections. Different nut types provide desired locking and fastening functions.
Flange Nuts
A flat round shape sits flush against fixture surfaces at assembly joints. Provides a tight fit when mated with a carriage bolt.
Serrated Flange Nuts
Sharp teeth on the flange grip into surfaces to prevent spinning and lock against vibrations. Used where excessive movement or vibration is expected.
Lock Nuts
Deformed threads resist loosening from vibrations. Ideal for securing parts that will experience stress from wind, seismic activity, or frequent adjustments like tilt mounts.
Slotted Nuts
Rectangular shape slots into fixtures and equipment frames. Permanently affixes to a base structure while allowing the mating bolt to be removed.
In addition to these foundational solar mounting fasteners, components like racking rails, clamps, and roof attachments rely on the proper use of screws, bolts, washers, and nuts to create safe and secure installations. Stainless steel hardware and UV-resistant components ensure long-lasting performance for decades of exposure to outdoor elements. With the right selection of mounting products, solar installers can efficiently assemble PV systems that will stand the test of time.
